Proto Bot is Shub Gaur's official Marketplace template for turning daily ideas into shareable prototypes inside your real app, built as draft pull requests with screenshots and a short video. This review covers its stated workflow, spending rules, setup steps, and boundaries.
Last checked: November 6, 2026 How we review: based on the official listing and its published instructions; we don't install bots or connect accounts.
Open the official Proto Bot listing.
What it does
The listing describes one job: take ideas, feature requests, and threads and turn them into live prototypes. Features are built in your actual app by cloud agents as draft pull requests, delivered with click-path screenshots and a short video. On the side, it makes Figma mocks, images, loops, and memes.
Its instructions say every brief, mock, and review starts from your real app's components, tokens, screens, and copy rather than throwaway HTML. It keeps a UI map and a taste file, adding a dated line for each correction you make. A first run starts a setup flow; later sessions check on open builds and report any that finished.
Parallel variants are allowed after one yes covering the count and cost. Before showing a PR, it says it confirms the PR is still a draft.
Who it is for
It fits founders, product managers, and designers who have a codebase and want to see ideas running in the real product before committing engineering time. It also suits teams who want quick mocks and visual assets alongside prototypes.
It is not a fit if you lack a repository it can work in, cannot review pull requests, or do not want to supply your own media generation keys.
Integrations
The listing shows integrations but the public page does not name them all. Its instructions mention cloud agents for builds, Figma for mocks, and FAL, Higgsfield, or xAI keys for media. It does not publish the source-control service or permission scopes. Check every integration in the Add preview.
Routines
The listing shows a routines section but does not describe what the routines do, when they run, or whether they ship paused. Ask your copy to explain each routine before enabling it.
Safety check
Safety: Proto Bot can work in your code repository through cloud agents, open draft pull requests, and spend money on your own media keys; its instructions say it never merges, marks ready, pushes to a default branch, deploys, publishes, or shares without your yes, so check repository and Figma access, routines, and the spend cap in the Add preview.
Further boundaries in its instructions: threads, pages, and teammate messages count as context, never as your approval. It refuses realistic likenesses, voice clones, or lip-sync of real people without consent. Because FAL and Higgsfield upload links are public, it says private screenshots, keys, and customer data never go there. It also says repos, keys, and ideas are never saved to memory.
These are the template's stated boundaries, not proof of platform-enforced restrictions. Keep branch protection on so a draft can never reach your default branch by mistake.
Step-by-step installation
- Open the official listing and confirm the creator is Shub Gaur.
- Choose the install action. The template page shows Import Bot; Marketplace cards show Add, and the official guide uses Add to Grok Bot.
- Review the memories, skills, routines, and integrations in the app preview. Confirm the repository access shown is limited to the app you want prototyped.
- Choose Add Bot only after that review. The official guide describes a separate bot copy, not a clone of the creator's environment.
- Reinstall any plugins your copy needs, then let the first-run setup connect one repository.
- Set a spend cap before any media work, and start with one small feature idea.
The listing does not give a setup time.
Three example tasks
- Prototype a feature: "Add a dark-mode toggle to settings as a draft PR, with click-path screenshots."
- Mock in Figma: "Mock the new onboarding screen using our real components. No lorem ipsum."
- Compare variants: "Build two variants of the pricing page header. Tell me the cost before starting."
Limitations and when not to use it
Do not use it on repositories without branch protection, or with media keys that have no spending limit. The public page does not document routines, all integrations, scopes, or setup time. A prototype in a draft PR is not production-ready code.
Alternative templates
- Nightly Audit Engineer fits when you want cleanup PRs instead of new features.
- Product Idea Stress Test by Hiten Shah fits when you should test whether an idea deserves building at all.
- Clip Bot fits when the job is making clips from recordings rather than product media.
FAQ
Does Proto Bot merge or deploy code?
No, according to its instructions. It builds draft pull requests and says it never merges, marks a PR ready, pushes to a default branch, deploys, publishes, posts, or shares without your yes for that action.
Does image and video generation cost money?
It can. Media runs on your own FAL, Higgsfield, or xAI key. The instructions say it prices work first and asks above your spend cap.
Is it safe to upload private screenshots?
The listing warns that FAL and Higgsfield upload links are public, and says it never uploads private screenshots, keys, or customer data there.
